Bug #: 42913 Summary: r600g: glx-swap-pixmap causes screen corruption Classification: Unclassified Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: debian@carbon-project.org
First: I don't think this is bug 40610 because I don't see a crash but screen corruption and (sometimes) the following lines in dmesg:
radeon 0000:01:00.0: r600_check_texture_resource:1346 texture invalid format 0 [drm:radeon_cs_ioctl] *ERROR* Invalid command stream !
But I'm no Mesa/Piglit expert, so my assumption might be wrong.
The Piglit test itself fails, the output is:
Probe at (0,0) Expected: 0.000000 1.000000 0.000000 0.000000 Observed: 0.000000 0.000000 1.000000 1.000000
Used stack: Mesa: Git/9ae10e9c libdrm: 2.4.27-1 Kernel: 3.1.1 X.org: 1.11.1.902-1
Let me know, if you need more information.
